Current conservation status
The conservation status of all known New Zealand vascular plant taxa at the rank of species and below were reassessed in 2017 using the New Zealand Threat Classification System (NZTCS). This report includes a statistical summary and brief notes on changes since 2012 and replaces all previous NZTCS lists for vascular plants. Authors: By Peter J. de Lange, Jeremy R. Rolfe, John W. Barkla, Shannel P. Courtney, Paul D. Champion, Leon R. Perrie, Sarah M. Beadel, Kerry A. Ford, Ilse Breitwieser, Ines Schönberger, Rowan Hindmarsh-Walls, Peter B. Heenan and Kate Ladley.

.Cream-flowered vine with variable shaped leaflets in threes
Endemic. North and South Islands. From Auckland area south to northern Westland and Canterbury.
Lowland forest and forest margins, especially forest margins, open spaces and streamsides.
Variable evergreen woody climber; stems to 5 m long, 5-10 mm diam. at base; branchlets grooved, sparsely hairy when young, becoming glabrous. Leaves 3-foliate, opposite, 3-10(-16) x (3-)4-8(-14) cm; petioles (1-)2-5(-7) cm long, stout, glabrous. Leaflets 14-55 x 9-28, simple to pinnate, simple leaflets lanceolate to deltoid, margins crenate, serrate or deeply pinnatifid to bipinnatifid, apices apiculate, base attenuate to truncate, petiolules 10-60 mm long, grooved, twining, glabrous or sparsely hairy, hairs white, becoming glabrate; midvein and secondary veins visible above, more obvious below; lamina thin to coriaceous, dark green to grey-green, tip acute, base truncate to subcordate, undersides paler. Juvenile leaves larger, thinner. Inflorescences unisexual, conspicuous, of solitary or 2-10-flowered clustered in leaf axils or in dichasial cymes of 5-10 flowers; pedicels 25-95 mm long moderately to densely hairy; inflorescence bracts 3-13(-18) x 1-4(-8), linear to elliptic, acute to obtuse, paired, united, inserted about middle of pedicel, glabrous to moderately hairy. Flowers spicey scented. Male to 4 cm diam., sepals 5-6, narrowly to broadly elliptic, lanceolate or ovate, imbricate, glabrous or sparsely silky hairy above (rarely glabrous above), silky hairy to hairy beneath, 10-25 x 3-13 mm, cream, base often flushed red-brown; stamens 20-37, anthers 2.4-3.5 mm long, filaments glabrous., 3-11 mm long. Female sepals 5-6(-7), similar to male, 13-25 x 3.8-7 mm; Carpels 35-48; staminodes 1-6. Achenes hairy, elliptic, or rarely narrowly elliptic, narrowed to apex, compressed, margin thickened and distinct, surface unornamented or occ. ridged, (2.6-)3.0-4.5(-5.1) mm long, styles (15-)20-35(-40) cm long at fruiting, white-plumose for most of length, glabrous or with short hairs at base.
Similar to the white larger-flowered C. paniculata. Also similar to both C. foetida and C. cunninghamii, both of which have brownish hairs on young leaves and elsewhere. Closest to C. petriei, from which it can be distinguished by the yellow-green evenly coloured and near-glabrous above sepals and the narrower more pointed floral bracts.
Pappate achenes are dispersed by wind (Thorsen et al., 2009).
clematis: From the Greek klema ‘vine’, alluding to the vine-like habit of many species
